“The Occupy Wall Street protests came to Washington today, as marchers gathered near the White House and President Barack Obama said the demonstrations are “giving voice” to frustrations with the financial system. “The American people understand that not everybody’s been following the rules, that Wall Street is an example of that,” Obama said at a White House press conference. He stopped short of endorsing the movement that began three weeks ago in Lower Manhattan and has spread to cities from Houston to San Francisco with the help of postings on Twitter and websites.”
